Domain and range of a function explained in plain English. Different ways to find the domain and range including graphs, "guess and check".
Not a function: “one to many“. In other words, let’s say you had one x-value that maps to many y-values. For example, — in coordinate notation — (2,1) and (2,10). If the first number (the x-value) repeats, then you do not have a function. To put that another way, ...
How can I graph f(x) = (sin x) x on [-5pi, 5pi] ? Using Desmos, how can we describe what the graph shows? How would we graph just q(x)? Explain how the graph of y = -3tan(1/2x) is related to the graph of the basic trigonometric function y = tan x. What is the ra...
Are you unable to read the number off of the graph? Which part made no sense? Jan 13, 2010 #6 Mark44 Mentor Insights Author 37,961 10,383 Simply by observing the graph you should be able to find b, c, and d in your equation f(x) = a(x -b)(x - c)(x - d). And...
Click here to watch it on YouTube.When you tackle a normal distribution problem in a statistics class, you’re trying to find the area under the curve. The total area is 100% (as a decimal, that’s 1). Normal distribution problems come in six basic types. How do you know that a...
